Drew Barrymore's PDA-Filled Roman Holiday (PHOTOS)
The hands-on couple spent the day taking in the sights with a friend, while stopping to enjoy some sweet kisses along the way.
They threesome hit up the Clemente for lunch, then went to the Pantheon, where Drew was obviously moved by the historic temple to the Roman gods. They moved on to the Trevi fountain, where they took photos and then did some shopping. At the end of the day, the romance continued with Will buying a bouquet of flowers for his lady love.
The two reportedly began their romance earlier this year, as they were spotted getting together in late February.
Drew had been on a travel kick lately, most recently went to Kenya to further her humanitarian work. The 36-year-old is an ambassador for the World Food Programme.
